XP per level in 4e is dependent on the amount of free alcohol the DM is provided each night. So a DM should take the encounter(s) XP multiply it by a baseline of 1.1 per ounce of actual alcohol (so 80 proof whisky would require 2.5 ounces to get the 1.1 multiplier, 5 ounces would give 1.21 multiplier, etc.) The multiplier only lasts as long as the alcohol is available though.
Since, thanks to Queen D and The Universe, we already know about the "times ten" rule (pay the DM a dollar, your roll counts as times ten), then do we call this the "times ten proof" rule?
